FIELD: chemistry.SUBSTANCE: composition for producing products from hard polymer foam includes: a) at least one polymer resin, b) surface-treated calcium carbonate, having a weighted average particle diameter d50 between 0.5 mcm and 0.9 mcm, measured by a sedimentation method, in an amount of at least 10 parts per 100 parts of at least one polymer resin (pts. wt) and c) a foaming agent in an amount of less than 1 pts. wt. The invention also relates to a product made of the hard polymer foam obtained from the said composition, a method of producing a product from the hard polymer foam and to the use of calcium carbonate.EFFECT: low density of a product made of hard polymer foam.24 cl, 2 dwg, 4 tbl |
